Final answer:
Anyone driving a motor vehicle must have a valid driver's license and proof of vehicle insurance. These requirements help ensure drivers are authorized and equipped to handle financial responsibilities in case of accidents.
Step-by-step explanation:
When driving a motor vehicle, it is required by law for the driver to have in their possession a valid driver's license and proof of insurance. A driver's license serves as a legal permit to operate a vehicle and confirms that the holder has passed the necessary tests to demonstrate their understanding of road rules and safety. Furthermore, a valid form of vehicle insurance is necessary to ensure financial responsibility in the event of an accident. This is typically mandated by state laws and helps protect not only the drivers but also other individuals and property that may be affected in a collision.
